TAS-20中文版的信度、效度分析

The Chinese version of the TAS-20: reliability and validity

目的 :建立多伦多述情障碍 2 0个条目量表 (TAS -2 0 )的中文版 ,并分析其信、效度。方法 :416名大学生完成了TAS -2 0 ,分析量表的内部一致性和重测信度、条目间平均相关系数、总分与各因子间的相关系数 ,并进行验证性因子分析。结果 :TAS -2 0中文版的Cronbach’sa系数为 0 83 ;重测信度为0 87;条目间平均相关系数在 0 13～ 0 3 2之间 ;总分与各因子的相关系数在 0 72～ 0 82之间 ,各因子间的相关系数在 0 2 9～ 0 5 4之间 ;条目对因子负荷系数在 0 2 5～ 0 76之间 ,复相关系数在 0 0 6～ 0 5 7之间 ;验证性因子分析的指标 :NFI ( 0 973 )、CFI ( 0 987)、TLI ( 0 984)、χ2 /df ( 1 781)、REMEA ( 0 0 5 5 )均符合测量学要求。结论 :TAS -2 0中文版具有良好的信、效度 ,在我国也是一种较好的述情障碍测评工具。

Objective:To develop the Chinese version of the twenty-item Toronto Alexithymia Scale (TAS-20) and examine its reliability and validity.Method:A sample of 416 undergraduate students was tested. We examined the Chinese version of the TAS-20's internal reliability and test-retest reliability. Using confirmatory factor analysis, we tested the three-factor model.Result:The Cronbach's a coefficient of the TAS-20 was 0.83; The test-retest reliability coefficient was 0.87; The mean interitem correlation coefficients ranged from 0.13 to 0.32; The correlation coefficients of the three factors with the total scale score ranged from 0.72 to 0.82, The correlation coefficients among the three factors ranged from 0.29 to 0.54; The factors loadings ranged from 0.25 to 0.76. The squared multiple correlations were 0.06～0.57. The NFI(0.973)?CFI (0.987)?TLI(0.984)?χ 2/df(1.781)?REMEA(0.055)all met the criteria standards for adequacy of fit.Conclusion:the Chinese version of the TAS-20 was a reliable and valid measure for assessing alexithymia in Chinese-speaking sample.
